This is a PostgreSQL DB, and is intended to persist information such as the following:

• PCI-Handler MS Config information (e.g., thresholds, timer values, OOF algorithm name, etc.)
• Pre-processing results and other related information (e.g., neighbor list)
• Buffered notifications (i.e., notifications not yet processed at all)
• State information
• Association between pnf-name and CellId

1.3. DMaaP Client

This is responsible for registering with the DMaaP client for the DMaaP notifications from SDN-R, and to Policy.

2. Core Logic components and Pre-processing algorithm

...

After sending the message to Policy, a status update is provided to the Main Thread for further actions.

Buffered notification handling

• If the main thread triggers a buffered notification to be handled, start buf_timer (if not started already) to buffer the notification (pre-configured value), if not already started (Note), and store the notification contents.
• Upon expiry of buf_timer, process the received (and stored) notifications by transitioning to Cluster Modification state.
• If new notifications are received when in this state, then check on whether a notification was received and buffered for the same cell earlier, and if yes, discard the earlier notification (i.e., retain only the latest unprocessed notification for a cell). Simply store the notification and remain in this state.
